From a FDACS press statement:
While the Florida Department of Agriculture & Consumer Services (FDACS) is still awaiting results from product sampling (which we hope to have in the coming days), we do have results from our environmental sampling at the Big Olaf processing facility. Of the 100 environmental samples collected, nine have come back positive for Listeria monocytogenes (I will note that there is one outstanding environmental sample that is taking longer to develop). With these results (attached), FDACS has issued a stop use order of the processing equipment where the Listeria monocytogenes was found. This will effectively shut down all operations at this processing facility, which had already been done voluntarily by the company.

Here are the test results:
